The handles extend at an angle of approximately 17 degrees from the horizontal so that the wrists remain straight while the tote is carried. The distance between the handles is set at shoulder width. The distance between the rod members is on the order of 12 inches or less to maintain a center of gravity close to the worker's body. One of several plastic containers or trays of differing depths, preferably on the order of 6 inches, may be snapped onto the frame. Tray side walls extend upwardly and diverge from the tray bottom to an upper edge location offset slightly inwardly and downwardly from the hand grip to provide substantial clearance for a gloved hand. Accessories, such as front brackets for hanging the tote from the upper edge of a shipping crate, may be attached to the metal rod portions of the frame by welding or other suitable method.
Description
1) Field of the Invention
The present invention relates generally to devices for carrying items, and, more specifically, to an ergonomically improved tote with handles.
2) Related Art
In many areas of industry, such as in manufacturing, processing or parts distribution, objects must be gathered or stored and moved by hand from one location to another in containers such as boxes, tubs or trays. A typical container often has a rolled top edge or similar structure which requires the fingers to lift and carry the load with no help from the thumb. The finger tips have only about twenty-five to thirty percent of the strength of the full hand, and therefore containers which rely on finger tip lift cause excessive stress and limit the amount of weight that can be safely lifted or carried.
Other types of containers which have hand cutouts on the side provide better use of full hand strength for lifting and carrying. However, as these types of containers are lifted, the wrist bends rather than remains straight. Bending of the wrist results in high physical stress, reduced hand strength, and reduced hand and eye coordination. Additional problems with cutouts include lack of clearance for easy insertion of a gloved hand and the relatively small contact area between the hand and the thin upper portion of the cutout which results in the topside of the handle cutting into the hand. The sharper the carrying edge that contacts the hand, the less load the hand can support.
Some containers include handles that require the hands to be spread widely during lifting and carrying. Large tray length with the resultant increased hand spread place more of the load on weaker muscles of the shoulder rather than on the strong bicep muscles and limits the load that can comfortably be carried.
Container width (front to back distance) directly influences load center of gravity. Many of the wider containers of the prior art cause more low back stress as the center of gravity moves forward.
It is therefore an object of the present invention to provide an improved tote or container which overcomes many or all of the aforementioned problems associated with prior art containers.
It is a further object of the present invention to provide an improved tote or container which significantly lessens wrist fatigue and better utilizes hand strength compared to at least most previously available totes and containers. It is another object to provide such a device which reduces stress on the hands, wrists and back.
It is still another object of the present invention to provide an improved tote or container having handles which accommodate a power grip with gloved hands. It is another object to provide such a device which reduces wrist stress, maximizes use of hand strength, and enhances hand and eye coordination.
It is yet another object of the invention to provide an improved ergonomic tote which is relatively simple and inexpensive in construction. It is another object to provide such a tote having a handle frame that easily accommodates different attachments and containers of differing depths.
A tote constructed in accordance with the teachings of the present invention includes a steel frame having transversely extending front and rear metal rod members connected by fore-and-aft extending side handle portions which include a hand grips of diameter of at least 1.25 inches for maximum use of hand strength. The handles extend at an angle of approximately 17 degrees from the horizontal so that the wrists remain straight while the tote is carried in a generally level attitude with the worker's arms fully extended. The distance between the handles is set at about 20 inches, which is approximately shoulder width for most workers. The distance between the rod members is on the order of 12 inches or less to maintain a center of gravity close to the worker's body.
One of several plastic containers of differing depths, preferably on the order of 6 inches, is attached to the metal rod members and extends downwardly therefrom to a container bottom. Sidewalls extend upwardly and diverge from the bottom to an upper edge location offset slightly inwardly and downwardly from the hand grip to provide substantial clearance for a gloved hand. Accessories, such as front brackets for hanging the tote from the upper edge of a shipping crate, may be attached to the metal rod portions of the frame by welding or other suitable method. The use of a common handle frame for different sizes of trays or containers simplifies construction, provides versatility and reduces manufacturing costs.
These and other objects, features and advantages of the present invention will become apparent to one skilled in the art upon reading the following detailed description in view of the drawings.
FIG. 1 is a perspective view of a tote constructed in accordance with the teachings of the present invention and attached to the upper edges of a shipping crate.
FIG. 2 is an end view of the tote of FIG. 1.
FIG. 3 is a top view of the tote of FIG. 1.
FIG. 4 is rear view of the tote taken generally along lines 4--4 of FIG. 3.
Referring now to the FIG. 1, therein is shown a tote 10 supported on the upper edge 12 of a shipping crate 14. The tote 10 includes a molded plastic container or tray 20 releasibly connected to an upper handle frame 22 which generally surrounds the entire upper portion of the container 20. Trays of different sizes can be selectively supported from the frame 22.
The upper frame 22 includes a forward metal rod member 26 (FIG. 3) having short rearwardly extending ends 27 and 28. The frame 22 also includes a rear metal rod member 30 having forwardly and upwardly extending ends 31 and 32. The rod members as shown are fabricated from rust-protected steel round of diameter of approximately 0.375 inch. The rod ends are transversely spaced from each other less than 20 inches, preferably about 18.25 inches.
Molded over the rod ends 27,28 and 31,32 are handle structures 41 and 42. The handle structure 42, which is essentially the mirror image of the handle structure 41, includes a rear horizontal portion 44 extending around and forwardly from the rod end 28 to an enlarged grip portion 46 which extends upwardly in the forward direction from portion 44 at an angle of approximately 17 degrees. The grip portion 46 has a length of approximately 6 inches and a diameter of approximately 1.25 inches. The diameter of the rear portion 44 is slightly less (on the order of 1.0 inch) and tapers at transition area 44t (FIG. 3) to the grip diameter. The tray 20 has a centerline 50, and a vertical plane (see 50p of FIG. 2) passing through the centerline 50 essentially bisects the top of the handle portion 46. The forward end 54 of the handle structure 42 tapers at 54t to a reduced diameter portion which surrounds the end 32 and terminates slightly forwardly of the metal rod member 30. The end 54 is angled downwardly from the horizontal and from the forward end of the grip portion 46. Bracket structure 60 is fixed to the metal rod member 30 and permits the tote to be supported from the edge 12 (FIG. 1).
The tray 20 includes a horizontal bottom 70 with front and rear walls 72 and 74 diverging in the upward direction to uppermost lipped portions 76 and 78, respectively, which extend parallel to the bottom 70. The lipped portions 72 and 74 snap over the rod members 26 and 30. The entire tray 20 may be replaced with a different tray simply by removing the upper frame from the lips and placing the lipped portions of the new tray over the rods 26 and 30.
The tray bottom 70 includes reinforcing ribs 96 for strength. A ticket or card holding bracket 98 is supported on the side wall 82 inwardly of the corresponding portion 46. A similar bracket 100 is supported on the opposite wall 80.
As can best be appreciated from FIG. 3, the upwardly diverging walls 80 and 82 and edges 84 and 86 provide the accommodation spaces 90 and 92 with hand clearance offset both vertically and horizontally from the grip portions 46. The angle of the grip portions 46 with respect to the horizontal permits the wrist to remain straight (FIG. 2) in the normal arms extended carrying position. The relatively large diameter of the grip portions 46 provides good use of hand strength. The front to back distance of the tote, which as noted above is preferably about 12 inches or less, maintains the center of gravity close to the body (FIG. 2) for better back comfort. The rear wall 74 is located close to the person at a location just below waist height.
Having described the preferred embodiment, it will become apparent that various modifications can be made without departing from the scope of the invention as defined in the accompanying claims.
